“…4 TiO 2 nanotube arrays were made through electrochemical oxidation of a Ti foil, henceforth denoted ATNTA (anodic TiO 2 nanotube arrays). The unique configuration of TiO 2 nanotube arrays on Ti foil 5,6 is extremely desirable for practical applications, such as photoassisted water splitting, 7,8 dye-sensitized solar cells, 9,10 photodegradation, 11 field emitters, 12 biosensors, 13 gas sensors, [14][15][16] cathodic protection, 17 etc. ATNTA can be used directly as an ideal electrode, in which Ti foil is the current collector and TiO 2 serves as the active material.…”

“…Herein, it can be suggested that the nanoporous-structured TNs derived from a two-step electrochemical anodization is possible to effectively provide cathodic protection for 304 SS in 0.5 M NaCl solution under irradiation and in the dark, even better than the performances of the typical single-step anodized TN films reported in recent publications. 28,29 …”

Highly ordered TiO 2 nanotube ͑TN͒ arrays with a regular top porous morphology were fabricated by a facile two-step electrochemical anodization in an ethylene glycol solution containing NH 4 F and H 2 O. The morphology, crystalline phase, and composition of the TN films were characterized systematically by scanning electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy, and ultraviolet-visible spectroscopy. The photoelectrochemical properties of the TNs in 0.5 M NaCl solution were evaluated through electrochemical measurements under illumination and dark conditions. The nanoporous TNs exhibited a drastically enhanced photocurrent in the UV light region. The electrode potentials of 304 stainless steel coupled with the TiO 2 nanotube arrays negative shift values are no less than 354 mV under a white light irradiation. The experimental results indicated that the photoelectrochemical performance of the nanoporous-structured TNs was markedly influenced by the crystallization and the novel porous nanotubular architecture. And the nanoporous-structured TNs with a comparable high aspect ratio were able to effectively function photogenerated cathodic protection for metals under UV and visible light illumination. It is possible for such photogenerated cathodic protection to last for a period of 24 h, even in darkness.TiO 2 as a wide bandgap semiconductor has been broadly investigated in water splitting, 1 dye-sensitized solar cells, 2,3 photocatalysis, 4 and sensors 5 because of its chemical stability and unique functional properties. Compared with nanoparticles, TiO 2 nanowires or nanotubes have been reported to be superior in photoelectrochemical performance. 6-9 The advantages of TiO 2 nanotubes on titanium substrates lie in its large surface area, high aspect ratio, open hollow structure, strong adhesion to the substrate, and excellent controllability. Considering the above advantages of TiO 2 , it is highly desirable to further develop other functional applications based on this interesting one dimensional ͑1D͒ nanostructure. [9][10][11][12][13][14] Recently, intensive efforts have been undertaken to develop the photogenerated cathodic protection of metals under ultraviolet ͑UV͒ illumination by pure nano structured TiO 2 or its composites with other dopants, which are coated on metal substrate. 15-27 Yuan and Tsujikawa 15 first reported the photocathodic protection of copper by using a sol-gel derived TiO 2 coating. In addition, the photocathodic protection of other materials, such as stainless steel 17,18 and carbon steel, 19 by using pure TiO 2 , TiO 2 -WO 3 , 22 TiO 2 -SnO 2 , 23-26 TiO 2 -CeO 2 composite films, 27 and TiO 2 nanotubes 28,29 have been extensively reported. The principle of photocathodic protection is that e − -h + pairs are created because of the particles transition between the bands; when TiO 2 coated or coupled to a metallic substrate is exposed to UV irradiation, the photogenerated electrons can fill into the metallic substrate and adjust its Fermi level, and thereby shift the ...

“…However, because of the wide band gap of TiO 2 (anatase 3.2 eV, rutile 3.0 eV), the low energy utilization and rapid recombination of photogenerated electrons and holes reduced the photocathodic protection effect of these films. To address these drawbacks, highly ordered TiO 2 nanotube films possessing superior charge transport properties were prepared by electrochemical anodization method [1,10,11] and a variety of strategies have been developed to improve the light absorption of TiO 2 , such as decorating with narrow band gap semiconductors (ZnSe, CdSe, CdS) [12][13][14][15], metals (Au, Co, Ag, Fe) [16][17][18][19], non-metals (graphene, N, Si) [20][21][22], dye-sensitization (bacteriochlorophyll-C, phthalocyanine, porphyrin) [23][24][25] and doping with polymer conductors (polyaniline, pyrrole) [26][27][28].…”
